Irrigation High Limit Constant Flow Valves – K Valve
Griswold Controls’ Irrigation High Limit Constant Flow Valves limit the flowrate (gallons per minute) to your exact need.
Today a maintenance person can change the flow on an irrigation zone by easily adjusting the valve with the handle, increasing or decreasing that particular zone. This creates a problem because the system is designed for a specific flow rate — adjusting the valve changes that zone’s performance.
Limiting the flowrate to design flow gives the designer and property manager confidence that their system is performing exactly to their criteria.
Valve Benefits
- No more overflow or underflow problems – flow is guaranteed to +/-5% regardless of pressure changes in the system
- No need to adjust the valve – flowrate comes preset from factory
- Easy to change the flowrate – in the 1/2″–3″ size you don’t need to remove the valve from the line
- Corrosion resistant – brass housing in 1/2″–3″ valves and epoxy-coated housing in 3″–20″ valves
